 ### Auto-fixed Issues
 
 **1. [Rule 1 - Bug] Lint warning — unused `calledActorId` in burst test**
+
 - **Found during:** Task 1 (RED)
 - **Issue:** `calledActorId` was destructured in test 1 but the assertion was missing, producing an unused-variable lint warning.
 - **Fix:** Added `expect(calledActorId).toBe(actorId)` — the burst test now also asserts self-suppression, not just the dedicated D-03 test.
